Forostar was the northernmost province of Númenor. It was a great north-pointing cape about 300 miles from base to tip, rising from infertile stony plains to chilly, windswept high-lands and ultimately towering sea-cliffs. The only named settlement in the province was Ondosto located in its south eastern quarter along the main road. The Tower on Sorontil built by Tar-Meneldur to observe the stars on the peak of Sorontil near the northern cape of the island, was also another noted feature of the province.
